There is tech at every track we go to but some do more than others. Mostly every track does ride heights, wheel base, scales, etc. Other tracks have done things such as fuel, compression, wiring, gears, axles, shocks, and wiring. Even though they do these things tracks are afraid to dq someone and lose them the next week in the pits because they will be mad. In my opinion rules are rules, if you are under weight or to low in height well take the hit and move on. Sometimes mistakes happen.
